Who makes Kirkland Signature Ladies' Active Legging?
No reliable public evidence identifies the manufacturer of Kirkland Signature Ladies' Active Legging as of July 6, 2026.
The common claim
What most answers say — and what the evidence supports
The dominant claim online is that Lululemon makes Kirkland Signature leggings - the viral '$19 Costco dupe of the $98 Align' - yet no tier 1-5 evidence supports it. In June 2025 Lululemon sued Costco in federal court (Central District of California), alleging that Kirkland versions of its apparel are unauthorized knockoffs and that Costco lets shoppers believe they share a manufacturer with Lululemon; the complaint does not claim Lululemon makes them and names no actual Kirkland legging manufacturer. Who actually makes Kirkland leggings is not publicly documented.
Evidence & sources
Costco does not disclose its suppliers, and no tier 1–5 source names the maker of this product. Below is the documented search — every database and record we checked, and what each one returned.
Costco.com product-detail 'mfName' (manufacturer-of-record) field, via Wayback Machine (costco.com blocks automated fetch) July 6, 2026
No archived snapshot of a current Kirkland women's legging product page exists in the 2025+ format that embeds the mfName catalog field. Only pre-2017 legging pages (e.g. items 972384, 1062338, 100287201) are captured, and they predate the mfName field. Costco's apparel PDPs do expose named vendors of record - the current Kirkland Women's Active Jogger (item 4000336053, snapshot 2025-10-30) lists mfName 'SHANGHAI SHENDA LLC' (Made in Vietnam) - but a jogger's vendor cannot be assigned to the legging. Reading the legging's own mfName requires a direct browser capture (flagged for Ian).
Lululemon Athletica Canada Inc. v. Costco Wholesale Corp. (U.S. District Court, Central District of California), federal complaint filed June 2025 July 6, 2026
Lululemon's 49-page complaint alleges Costco's Kirkland Signature apparel copies Lululemon designs and that Costco lets shoppers believe the Kirkland items share a manufacturer with Lululemon - it explicitly frames them as unauthorized 'knockoffs,' the opposite of a supply relationship, and names no actual Kirkland legging manufacturer. This is the strongest available rebuttal of the viral 'Lululemon makes Kirkland leggings' claim. Reported by CNN (2025-06-30), NPR (2025-07-01), and others; the named dupes are mostly branded-vendor items (Danskin, Jockey, Spyder, Hi-Tec) plus a Kirkland '5 Pocket Performance Pant.'
CPSC recall database (SaferProducts.gov) July 6, 2026
No recalls for Kirkland Signature leggings or women's activewear; the handful of 'Kirkland' recalls on file are unrelated (prosecco bottles, cookware, non-Costco Kirkland's furniture). No supplier surfaced via the recall route.
News and fact-check sweep (Parade fact-check; CNN, NPR, ABC, Entrepreneur lawsuit coverage; trade press) July 6, 2026
Parade's 'Are Costco's Kirkland leggings really made by Lululemon?' fact-check and the 2025 lawsuit coverage all decline to name the actual maker; every mainstream treatment centers on the Lululemon dupe comparison and the litigation, not on a documented Kirkland legging supplier.
ImportYeti / US customs bills of lading (tier-5 import route) July 6, 2026
No Costco Kirkland-legging supplier signal retrievable; Costco routes apparel through vendor-of-record shells and freight forwarders, so the customs route is structurally weak for this category and returned nothing that names a legging maker.
Community/rumor scan (Reddit r/Costco, TikTok dupe posts, content-mill listicles) July 6, 2026
The near-universal claim is that Lululemon makes the Kirkland leggings (the '$19 Align dupe'), which the June 2025 Lululemon lawsuit directly contradicts. No consistent alternative maker is named; the rumor landscape collapses to the debunked Lululemon claim.
